DESCRIPCIONDESCRIPTION
Dispositivo para la aplicacion de un material viscoso en el canto de una pieza Campo de aplicacion tecnicaDevice for the application of a viscous material in the edge of a piece Technical field of application
La presente invencion se refiere a un dispositivo para la aplicacion de un material viscoso, especialmente un adhesivo, en el canto de una pieza.The present invention relates to a device for the application of a viscous material, especially an adhesive, in the edge of a piece.
La aplicacion de materiales viscosos como, por ejemplo, adhesivos en cantos de piezas plantea elevados requisitos al mecanismo de aplicacion, ya que solo pueden tolerarse pequenas desviaciones de alineacion con el canto y se debe lograr un recubrimiento completo del canto de la pieza. Por ejemplo, los cantos de piezas de CFK fresadas (CFK: plastico reforzado con fibra de carbono) deben sellarse para evitar la corrosion. El sellado se puede realizar de forma manual, automatizada o tambien parcialmente automatizada con un aplicador adecuado.The application of viscous materials such as, for example, adhesives in part edges poses high requirements to the application mechanism, since only small deviations from alignment with the edge can be tolerated and a complete coating of the part edge must be achieved. For example, the edges of milled CFK parts (CFK: carbon fiber reinforced plastic) must be sealed to prevent corrosion. Sealing can be done manually, automated or also partially automated with a suitable applicator.
Elevadas tasas de ciclo requieren una solucion de automatizacion o automatizacion parcial, por ejemplo, con ayuda de un robot, ya que un sellado manual requiere mucho tiempo y, por tanto, no es economicamente eficiente. Los aplicadores utilizados hasta ahora para la aplicacion automatizada de adhesivo tienen frecuentemente la desventaja de que la boquilla, en caso de piezas con ciertas tolerancias, no pueden seguir las desviaciones del canto de la pieza. La consecuencia es un contacto no deseado entre la boquilla y la pieza o una separacion demasiado grande respecto a la pieza si la trayectoria del robot esta predeterminada. Ademas, muchos aplicadores y boquillas tradicionales no pueden operar en huecos estrechos de las piezas.High cycle rates require a solution of automation or partial automation, for example, with the help of a robot, since a manual sealing requires a lot of time and, therefore, is not economically efficient. The applicators used so far for the automated application of adhesive frequently have the disadvantage that the nozzle, in case of parts with certain tolerances, cannot follow the deviations of the edge of the piece. The consequence is an unwanted contact between the nozzle and the part or a too large separation from the part if the robot's path is predetermined. In addition, many traditional applicators and nozzles cannot operate in narrow gaps of the parts.
Otro problema resulta del hecho de que los cantos de los materiales compuestos modernos, por ejemplo, CFK, presentan diferentes anchuras de canto debido a su estructura variable. La programacion de una trayectoria de robot para una alineacion centrada del aplicador es correspondientemente compleja. Existe la posibilidad de utilizar un sistema de sensores adecuado, que envie senales correctivas para una correccion de altura y, dado el caso, correccion lateral, directamente al sistema de control del robot. No obstante, para el sistema de sensores se debe contar con suficiente espacio. Ademas, un sistema de control de sensores es muy costoso y complejo y puede causar importantes retrasos temporales.Another problem results from the fact that the edges of modern composite materials, for example, CFK, have different edge widths due to their variable structure. Programming a robot path for a centered alignment of the applicator is correspondingly complex. There is the possibility of using a suitable sensor system, which sends corrective signals for a height correction and, if necessary, lateral correction, directly to the robot control system. However, sufficient space must be available for the sensor system. In addition, a sensor control system is very expensive and complex and can cause significant temporary delays.
Durante la aplicacion de adhesivo surge ademas el problema de que el cordon de adhesivo aplicado con las boquillas utilizadas hasta el momento, en caso de cantos de piezas estrechos y aunque se utilicen boquillas de ranura ancha, generalmente tiene una forma semicircular y los cantos de las superficies de la pieza frecuentemente no se llegan a recubrir. Sin embargo, para sellar los cantos logrando un recubrimiento completo de la superficie seria necesaria una seccion en forma de lente o de segmento circular plano.During the application of adhesive, there is also the problem that the adhesive cord applied with the nozzles used so far, in case of narrow piece edges and although wide slot nozzles are used, generally has a semicircular shape and the edges of the Workpiece surfaces are often not covered. However, to seal the edges achieving a complete surface coating, a section in the form of a lens or flat circular segment would be necessary.
Debido a los problemas anteriormente mencionados, los cantos de las piezas de CFK fresadas, con accesibilidad limitada, y los huecos de las piezas se sellaban hasta ahora generalmente de forma manual. Los cantos de las piezas con huecos y radios muy estrechos se sellan exclusivamente de forma manual. Los adhesivos se aplican manualmente con pinceles o a partir de cartuchos. Luego, el cordon de adhesivo semicircular es distribuido por el canto de la pieza con un rodillo y el adhesivo en exceso, que fluye por los lados de las piezas o por superficies que no deben recubrirse, se limpia manualmente.Due to the aforementioned problems, the edges of the milled CFK pieces, with limited accessibility, and the voids of the pieces were sealed until now generally manually. The edges of the pieces with gaps and very narrow radii are sealed exclusively manually. Adhesives are applied manually with brushes or from cartridges. Then, the semicircular adhesive cord is distributed by the edge of the piece with a roller and the excess adhesive, which flows along the sides of the pieces or surfaces that should not be coated, is cleaned manually.
El documento US 4778642 muestra una boquilla para la aplicacion de un material viscoso, que presenta varias aberturas de boquilla adicionales para influenciar la aplicacion de material con una corriente de aire. La abertura de la boquilla para la aplicacion de material esta rodeada por cuatro boquillas de aire, que durante la aplicacion de material soplan oblicuamente sobre el cordon de material que sale de la boquilla y ya lo moldean antes de la aplicacion. Una tecnica de este tipo se conoce tambien de las denominadas boquillas de torbellino. En la boquilla de este documento, adicionalmente estan dispuestas otras boquillas de aire, que se encuentran a una mayor distancia de la abertura de boquilla para la aplicacion de material y actuan sobre la forma del cordon de material ya aplicado. Los problemas relacionados con la aplicacion de un material viscoso en cantos de piezas, asi como en huecos estrechos de piezas o en cantos de piezas con radios estrechos no se comentan en este documento. La boquilla representada tampoco es adecuada para este tipo de aplicaciones debido al tamano que adopta a causa de las diferentes aberturas de boquilla.US 4778642 shows a nozzle for the application of a viscous material, which has several additional nozzle openings to influence the application of material with an air current. The opening of the nozzle for the application of material is surrounded by four air nozzles, which during the application of material blow obliquely on the cord of material that comes out of the nozzle and already mold it before application. A technique of this type is also known as the so-called vortex nozzles. In the nozzle of this document, other air nozzles are additionally arranged, which are located at a greater distance from the nozzle opening for the application of material and act on the shape of the cord of material already applied. Problems related to the application of a viscous material in parts, as well as in narrow holes of parts or in parts of narrow-spoke parts are not discussed in this document. The represented nozzle is also not suitable for this type of applications due to the size it adopts because of the different nozzle openings.
Del documento DE 102004039684, que da a conocer un dispositivo segun el preambulo de la reivindicacion 1, se conoce un dispositivo de formacion de linea de desempanado, en el que un cabezal de aplicacion es guiado con la ayuda de un brazo de robot sobre una placa de resina, sobre la cual se debe aplicar una pasta conductiva. El cabezal de aplicacion presenta una boquilla, asi como una pieza de contacto unida a la boquilla. A traves de un mecanismo de deslizamiento con muelle, la pieza de contacto es presionada contra la placa de resina asegurando una separacion constante entre la boquilla y la placa de resina durante la aplicacion.From DE 102004039684, which discloses a device according to the preamble of claim 1, a de-icing line formation device is known, in which an application head is guided with the help of a robot arm on a plate of resin, on which a conductive paste must be applied. The application head has a nozzle, as well as a contact piece attached to the nozzle. Through a spring sliding mechanism, the contact piece is pressed against the resin plate ensuring a constant separation between the nozzle and the resin plate during application.
El objetivo de la presente invencion consiste en poner a disposicion un dispositivo para la aplicacion de un material viscoso, especialmente un adhesivo, sobre cantos de piezas, que permita un recubrimiento mejorado de los cantosThe objective of the present invention is to make available a device for the application of a viscous material, especially an adhesive, on parts edges, which allows an improved coating of the edges

Representacion de la invencionRepresentation of the invention
El objetivo se consigue con el dispositivo de aplicacion segun la reivindicacion 1. Las configuraciones ventajosas del dispositivo son objeto de las reivindicaciones dependientes o se desprenden de la siguiente descripcion y los ejemplos de realizacion.The objective is achieved with the application device according to claim 1. The advantageous configurations of the device are subject to the dependent claims or are apparent from the following description and the examples of embodiment.
El dispositivo propuesto se utiliza preferentemente con una boquilla combinada, que presenta un primer canal de boquilla para el material viscoso, que termina en una primera abertura de boquilla, y un segundo canal de boquilla para un medio gaseoso, especialmente para aire, que termina en una segunda abertura de boquilla. Ambos canales de boquilla discurren en la boquilla combinada en un determinado angulo entre si, que es de entre 0° y 10°, preferentemente entre 0° y 5°. Ambas aberturas de boquilla son realizadas como ranuras anchas y presentan por tanto mayor anchura que longitud. Ambas aberturas de boquilla estan dispuestas en direccion longitudinal una tras la otra a una distancia central, que es de entre 3 y 5 mm.The proposed device is preferably used with a combined nozzle, which has a first nozzle channel for the viscous material, which ends in a first nozzle opening, and a second nozzle channel for a gaseous medium, especially for air, which ends in a second nozzle opening. Both nozzle channels run in the combined nozzle at a certain angle to each other, which is between 0 ° and 10 °, preferably between 0 ° and 5 °. Both nozzle openings are made as wide grooves and therefore have greater width than length. Both nozzle openings are arranged in a longitudinal direction one after the other at a central distance, which is between 3 and 5 mm.
Gracias a esta realizacion de la boquilla como boquilla combinada, preferentemente en una pieza, con dos boquillas de ranura ancha muy cercanas una de la otra, se consigue un sellado de cantos automatizado, sin contacto, economico, con cordon de material plano y por tanto cantos de piezas bien recubiertos, que no requieren ningun tipo de trapor manual posterior o proceso de limpieza posterior. El material viscoso, por ejemplo, un adhesivo, es aplicado por la primera boquilla de ranura ancha sobre el canto de la pieza. Directamente despues, a una distancia reducida y fija, le sigue la segunda boquilla de ranura ancha para el flujo de gas o aire, que sopla sobre el cordon de material ya aplicado ensanchandolo y aplanandolo. El cordon mas plano proporciona un mejor recubrimiento de los cantos de la pieza. La eleccion de aberturas de boquilla de ranura ancha permite la aplicacion del material viscoso con diferentes anchuras y por tanto una adaptacion a las respectivas dimensiones del canto de la pieza. La anchura de aplicacion se puede influenciar a traves de los parametros de proceso, como por ejemplo, ajustando la velocidad de avance y el flujo de masa del material que sale. La distancia reducida entre ambas aberturas de boquilla y los canales de boquilla preferentemente paralelos, o al menos practicamente paralelos, permiten realizar una boquilla muy compacta, con la que es posible aplicar el material tambien en huecos de piezas o radios estrechos.Thanks to this embodiment of the nozzle as a combined nozzle, preferably in one piece, with two wide groove nozzles very close to each other, an economical, contactless, economical edge sealing is achieved, with flat material cord and therefore edges of well-coated parts, which do not require any type of manual rear racking or subsequent cleaning process. The viscous material, for example, an adhesive, is applied by the first wide groove nozzle on the edge of the piece. Directly thereafter, at a reduced and fixed distance, the second wide groove nozzle for the flow of gas or air follows, which blows on the cord of material already applied by widening and flattening it. The flatter cord provides a better coating of the edges of the piece. The choice of wide groove nozzle openings allows the application of the viscous material with different widths and therefore an adaptation to the respective dimensions of the part edge. The application width can be influenced through the process parameters, such as by adjusting the feed rate and mass flow of the material coming out. The reduced distance between both nozzle openings and the preferably parallel, or at least practically parallel, nozzle channels allow a very compact nozzle to be made, with which it is possible to apply the material also in gaps of parts or narrow radii.
La anchura de las aberturas de boquilla es preferentemente de entre 3 y 6 mm, la longitud < 2 mm. La segunda abertura de boquilla esta dispuesta preferentemente desplazada hacia atras en una distancia de aproximadamente 4 ± 1 mm en direccion paralela al eje longitudinal del primer canal de boquilla o bien de la normal a la superficie del canto de la pieza para lograr una influencia optima sobre el cordon de material aplicado a traves del flujo de gas o aire. Por lo tanto, la salida de aire esta dispuesta aproximadamente 3-4 mm mas alta respecto a la superficie de la pieza que la salida de adhesivo.The width of the nozzle openings is preferably between 3 and 6 mm, the length <2 mm. The second nozzle opening is preferably disposed backwards by a distance of approximately 4 ± 1 mm in a direction parallel to the longitudinal axis of the first nozzle channel or from the normal to the surface of the part edge to achieve an optimal influence on the cord of material applied through the flow of gas or air. Therefore, the air outlet is arranged approximately 3-4 mm higher with respect to the surface of the piece than the adhesive outlet.
Para la aplicacion del material viscoso, por ejemplo, un adhesivo, sobre el canto de una pieza se recomienda el dispositivo segun la invencion, a continuacion tambien denominado “aplicador”. Este dispositivo se desplaza durante la aplicacion en una direccion de avance a lo largo del canto de la pieza sobre el cual se debe aplicar el material viscoso. Por canto de la pieza se debe entender en este sentido un lado estrecho de la pieza o de una zona de la pieza, por ejemplo, el lado estrecho de una placa o un cristal. El dispositivo comprende la boquilla para el material viscoso, que esta montada en un soporte de boquilla. Un rodillo guia (diabolo) esta fijado a la boquilla o al soporte de boquilla de forma que, para aplicar el material viscoso, se puede colocar sobre el canto y desplazarse a lo largo del mismo. El rodillo guia esta dispuesto de forma que garantiza una posicion definida de la boquilla respecto al canto durante la aplicacion, especialmente un centrado de la boquilla respecto al canto, asi como una separacion constante. El soporte de boquilla esta unido a traves de un mecanismo de union a un elemento de conexion, a traves del cual el dispositivo o el aplicador se puede conectar a un dispositivo de manipulacion, un asidero o un cartucho. De este modo, el aplicador se puede conectar, por ejemplo, a un brazo de robot y ser guiado por el brazo de robot para una aplicacion automatica del material viscoso. El mecanismo de union del dispositivo propuesto se realiza de forma que, al menos en la direccion hacia el canto de la pieza, es decir, en una direccion paralela a la normal a la superficie del canto de la pieza, permita un movimiento relativo del soporte de boquilla o de la boquilla respecto al elemento de conexion, y presenta un mecanismo de muelle, mediante el cual el rodillo guia es presionado durante la aplicacion contra el canto. La capacidad de movimiento del soporte de boquilla o de la boquilla en direccion del canto se elige de forma que sea posible compensar ciertas tolerancias de la pieza a lo largo del canto a traves de este movimiento. Esto permite lograr un sellado completamente o parcialmente automatico del canto de la pieza. El rodillo guia garantiza el guiado exacto de la boquilla a lo largo del canto de la pieza. La capacidad de movimiento del soporte de boquilla respecto al elemento de conexion o del dispositivo de manipulacion, el asidero o el cartucho, al que esta unido el aplicador, permite lograr una separacion constante de la boquilla respecto al canto de la pieza, incluso si existen ciertas tolerancias de la pieza, sin necesidad de utilizar para ello complejos sistemas de sensores.For the application of the viscous material, for example, an adhesive, on the edge of a piece the device according to the invention is recommended, then also called "applicator". This device moves during the application in a direction of advance along the edge of the piece on which the viscous material should be applied. In this sense, the narrow side of the piece or an area of the piece, for example, the narrow side of a plate or glass, should be understood in this sense. The device comprises the nozzle for the viscous material, which is mounted on a nozzle holder. A guide roller (diabolo) is fixed to the nozzle or nozzle holder so that, to apply the viscous material, it can be placed on the edge and moved along it. The guide roller is arranged so as to guarantee a defined position of the nozzle with respect to the edge during application, especially a centering of the nozzle with respect to the edge, as well as a constant separation. The nozzle holder is connected through a joint mechanism to a connecting element, through which the device or the applicator can be connected to a handling device, a handle or a cartridge. In this way, the applicator can be connected, for example, to a robot arm and guided by the robot arm for an automatic application of the viscous material. The mechanism of union of the proposed device is carried out in such a way that, at least in the direction towards the edge of the piece, that is, in a direction parallel to that normal to the surface of the edge of the piece, it allows a relative movement of the support of nozzle or nozzle with respect to the connecting element, and has a spring mechanism, by which the guide roller is pressed during the application against the edge. The movement capacity of the nozzle holder or of the nozzle in the direction of the edge is chosen so that it is possible to compensate for certain tolerances of the part along the edge through this movement. This allows a completely or partially automatic sealing of the edge of the piece. The guide roller guarantees the exact guidance of the nozzle along the edge of the piece. The movement capacity of the nozzle holder with respect to the connection element or the handling device, the handle or the cartridge, to which the applicator is attached, allows a constant separation of the nozzle from the part edge, even if they exist certain tolerances of the piece, without using complex sensor systems.
En el dispositivo propuesto, el rodillo guia puede estar dispuesto en direccion de avance delante o detras de la boquilla. Una disposicion delante de la boquilla se elige preferentemente cuando se va a influenciar o bien moldear el cordon de material aplicado a traves de una corriente de aire o gas desde una abertura adicional de la boquilla. En el caso de una disposicion detras de la boquilla, el rodillo guia se realiza, o especialmente se conforma, de modoIn the proposed device, the guide roller may be arranged in the forward direction in front of or behind the nozzle. An arrangement in front of the nozzle is preferably chosen when the cord of material applied through a stream of air or gas is to be influenced or molded from an additional opening of the nozzle. In the case of an arrangement behind the nozzle, the guide roller is made, or especially shaped, so

que el rodillo guia influya o bien moldee el cordon de material aplicado con la boquilla. Es decir que, en este caso, el rodillo guia tiene una doble funcion que consiste, por un lado, en garantizar una posicion definida de la boquilla respecto al canto durante la aplicacion y, por otro lado, en moldear el cordon de material aplicado. Por moldeado se entiende aqui una rectificacion o alisado del cordon de material.that the guide roller influences or molds the cord of material applied with the nozzle. That is to say, in this case, the guide roller has a double function that consists, on the one hand, in guaranteeing a defined position of the nozzle with respect to the edge during the application and, on the other hand, in molding the cord of applied material. By molding is meant here a rectification or smoothing of the material cord.
De este modo, el soporte de boquilla se puede realizar correspondientemente estrecho, lo que permite realizar una aplicacion de material tambien en huecos estrechos de las piezas.In this way, the nozzle holder can be made correspondingly narrow, which allows an application of material also in narrow gaps of the parts.
El mecanismo de union se puede realizar de diferentes maneras. En una configuracion ventajosa, el mecanismo de union se realiza como palanca acodada, en la que el soporte de boquilla representa un brazo de esta palanca acodada o esta fijado a ella. Como boquilla se puede utilizar, por ejemplo, una boquilla de ranura ancha, a traves de la cual se aplica el material viscoso sobre el canto de la pieza. Mediante la palanca acodada se consigue que el soporte de boquilla pueda moverse con la boquilla en direccion de la normal a la superficie del canto de la pieza. Este aplicador se conecta, por ejemplo, a un equipo de automatizacion (p. ej. un robot) y al sistema de dosificacion para el material viscoso. El rodillo guia toca el canto de la pieza y persigue o antecede a la boquilla en la direccion de desplazamiento o avance del aplicador. Las tolerancias de la pieza en direccion normal son compensadas por el mecanismo de muelle en la palanca acodada. Por lo tanto, gracias al rodillo guia, el aplicador esta en contacto continuo con el canto de la pieza.The union mechanism can be performed in different ways. In an advantageous configuration, the union mechanism is realized as a bent lever, in which the nozzle holder represents an arm of this bent lever or is fixed thereto. As a nozzle, for example, a wide groove nozzle can be used, through which the viscous material is applied on the edge of the piece. By means of the angled lever it is possible that the nozzle holder can move with the nozzle in the direction of the normal to the surface of the edge of the piece. This applicator is connected, for example, to an automation equipment (eg a robot) and to the dosing system for the viscous material. The guide roller touches the edge of the part and chases or precedes the nozzle in the direction of travel or advance of the applicator. The tolerances of the part in the normal direction are compensated by the spring mechanism on the bent lever. Therefore, thanks to the guide roller, the applicator is in continuous contact with the edge of the piece.
En una realizacion adicional de esta configuracion, al aplicador esta fijado un sensor para registrar los movimientos de la palanca acodada, cuyos datos de medicion pueden ser utilizados para controlar el equipo de automatizacion. De este modo es posible, por ejemplo, registrar el movimiento de la palanca acodada con un laser de distancia a modo de sensor, para luego transmitir las desviaciones respecto a la trayectoria previamente programada del equipo de automatizacion al sistema de control de la trayectoria, que entonces corrige la trayectoria de forma correspondiente.In a further embodiment of this configuration, a sensor is attached to the applicator to record the movements of the angled lever, whose measurement data can be used to control the automation equipment. In this way it is possible, for example, to register the movement of the bent lever with a distance laser as a sensor, and then transmit the deviations from the previously programmed path of the automation equipment to the path control system, which then correct the trajectory accordingly.
Con este aplicador se puede lograr un sellado de cantos automatizable en piezas con ciertas tolerancias, radios estrechos y accesibilidad limitada. Una gran ventaja consiste en la posibilidad de una realizacion estrecha de la punta del aplicador, que tambien permite un alcance en huecos y recortes con radios reducidos. Mediante el rodillo guia o de presion, el aplicador tiene contacto con la pieza de forma continua y controlada por fuerza de muelle, y sigue el canto de la pieza incluso si la pieza presenta desviaciones en direccion normal a la superficie.With this applicator you can achieve an automated edge sealing in parts with certain tolerances, narrow radii and limited accessibility. A great advantage consists in the possibility of a narrow realization of the tip of the applicator, which also allows a reach in holes and cuts with reduced radii. By means of the guide or pressure roller, the applicator has contact with the piece continuously and controlled by spring force, and follows the edge of the piece even if the piece shows deviations in the normal direction to the surface.
En otra configuracion, el mecanismo de union se realiza de forma que pueda moverse, no solo en paralelo a la normal a la superficie del canto de la pieza, sino tambien perpendicular a la normal a la superficie y a la direccion de avance. Para cada movimiento esta integrado un mecanismo de muelle que presiona el rodillo guia contra el canto de la pieza o actua en contra de una desviacion de una posicion central del rodillo guia. Tambien en este caso se utiliza preferentemente una boquilla de ranura ancha para aplicar el material viscoso. El aplicador puede estar conectado a un equipo de automatizacion, como por ejemplo, un robot o un sistema de coordenadas cartesianas tipo portico, asi como a un sistema de dosificacion correspondiente para el material viscoso. El rodillo guia toca el canto de la pieza y persigue o antecede a la boquilla en la direccion de desplazamiento o avance durante la aplicacion del material viscoso. Gracias a que el soporte de boquilla se puede mover en dos direcciones espaciales respecto al elemento de conexion es posible compensar las tolerancias de la pieza, tanto en direccion normal, como tambien en direccion ortogonal a la direccion de avance mediante el mecanismo de muelle de retorno automatico. El propio rodillo guia esta en contacto continuo con el canto de la pieza durante la aplicacion y proporciona una separacion constante de la boquilla respecto a la pieza gracias al acoplamiento mecanico con la boquilla. Tampoco en esta configuracion es necesario un complejo sistema de sensores para mantener una posicion definida de la boquilla respecto al canto de la pieza.In another configuration, the joining mechanism is carried out so that it can move, not only parallel to the normal surface of the piece, but also perpendicular to the normal surface and the direction of advance. For each movement a spring mechanism is integrated that presses the guide roller against the edge of the piece or acts against a deviation from a central position of the guide roller. Also in this case, a wide groove nozzle is preferably used to apply the viscous material. The applicator can be connected to an automation equipment, such as a robot or a portic Cartesian coordinate system, as well as a corresponding dosing system for the viscous material. The guide roller touches the edge of the piece and chases or precedes the nozzle in the direction of travel or advance during the application of the viscous material. Thanks to the fact that the nozzle holder can be moved in two spatial directions with respect to the connecting element, it is possible to compensate the workpiece tolerances, both in the normal direction, and also in the direction orthogonal to the direction of advancement by the return spring mechanism automatic. The guide roller itself is in continuous contact with the edge of the piece during application and provides a constant separation of the nozzle from the piece thanks to the mechanical coupling with the nozzle. Nor in this configuration is a complex system of sensors necessary to maintain a defined position of the nozzle with respect to the edge of the piece.
Con este aplicador se puede lograr un sellado de cantos automatizable y sin sensores en piezas con tolerancias y anchura de canto variable. Una gran ventaja consiste en que se puede prescindir de un control mediante sensores relativamente complejo evitando retrasos temporales. El aplicador tiene contacto con la pieza de forma continua y controlada por fuerza de muelle, y sigue el canto de la pieza incluso en caso de oscilaciones del dispositivo de manipulacion a causa de inercias de masa o resonancias.With this applicator you can achieve an automated edge sealing without sensors in parts with tolerances and variable edge width. A great advantage is that control can be dispensed with by relatively complex sensors avoiding temporary delays. The applicator has contact with the piece continuously and controlled by spring force, and follows the edge of the piece even in case of oscillations of the manipulation device due to mass inertia or resonance.
En otra configuracion, el mecanismo de union se realiza como guia en paralelogramo. La guia en paralelogramo permite realizar un movimiento angular de, por ejemplo, ± 10 mm y por tanto un desplazamiento de la boquilla o del soporte de la boquilla paralelo a la normal a la superficie del canto de la pieza de aproximadamente 20 mm. El desplazamiento tambien es controlado mediante un muelle de retorno automatico para poder compensar las correspondientes tolerancias de las piezas. En la configuracion preferida, el elemento de conexion de este aplicador se realiza de forma que se pueda conectar a un cartucho para el material que se va a aplicar, por ejemplo un adhesivo o sellador. Preferentemente, el aplicador se enrosca directamente a la pistola de cartuchos. Gracias al desplazamiento de retorno automatico debido a la guia en paralelogramo en combinacion con un mecanismo de muelle, tambien es posible compensar una inexactitud del operador durante la aplicacion manual sobre cantos con radios estrechos con la ayuda del muelle o del mecanismo de muelle. Para ello, el operador presiona el rodillo guia contra el canto de la pieza al comienzo del proceso de aplicacion y coloca el paralelogramo en la posicion central. Gracias al pretensado del muelle en la posicion central del paralelogramo, se asegura un contacto continuo delIn another configuration, the union mechanism is performed as a guide in parallelogram. The parallelogram guide allows an angular movement of, for example, ± 10 mm and therefore a displacement of the nozzle or the nozzle holder parallel to the normal surface of the part edge of the piece of approximately 20 mm. The displacement is also controlled by an automatic return spring to compensate for the corresponding tolerances of the parts. In the preferred configuration, the connection element of this applicator is made so that it can be connected to a cartridge for the material to be applied, for example an adhesive or sealant. Preferably, the applicator is screwed directly to the cartridge gun. Thanks to the automatic return movement due to the parallelogram guide in combination with a spring mechanism, it is also possible to compensate for an inaccuracy of the operator during the manual application on edges with narrow radii with the help of the spring or the spring mechanism. To do this, the operator presses the guide roller against the edge of the part at the beginning of the application process and places the parallelogram in the central position. Thanks to the spring preloading in the central position of the parallelogram, a continuous contact of the

rodillo guia o de presion con la pieza y el operador se puede concentrar por completo en la posicion de la boquilla respecto a la pieza en direccion de la curva. Durante el proceso de aplicacion debe procurar mantener la posicion central del paralelogramo. El rodillo guia siempre persigue o antecede a la boquilla en direccion de desplazamiento y ayuda a estabilizar la trayectoria en direccion tangencial. La boquilla de ranura ancha preferentemente utilizada se puede sustituir en esta, asi como tambien en otras configuraciones, por una boquilla redonda para cantos muy estrechos.guide or pressure roller with the part and the operator can concentrate completely on the position of the nozzle with respect to the part in the direction of the curve. During the application process you should try to maintain the central position of the parallelogram. The guide roller always chases or precedes the nozzle in the direction of travel and helps stabilize the trajectory in the tangential direction. The preferably used wide groove nozzle can be replaced in this, as well as in other configurations, by a round nozzle for very narrow edges.
Este aplicador permite realizar un sellado economico y semiautomatico de cantos de piezas con radios estrechos en huecos. Las ventajas mas importantes son el contacto continuo con la pieza gracias al paralelogramo, asi como el guiado tangencial gracias al rodillo guia, que permiten realizar un sellado acelerado de cantos de piezas, incluso si se realiza manualmente.This applicator allows economical and semi-automatic sealing of parts with narrow gaps. The most important advantages are the continuous contact with the piece thanks to the parallelogram, as well as the tangential guidance thanks to the guide roller, which allow an accelerated sealing of parts edges, even if done manually.
El dispositivo propuesto, asi como la boquilla combinada utilizada preferentemente con este dispositivo se pueden utilizar, por ejemplo, para el sellado de cantos de piezas de puertas o lunas para aplicaciones del sector automovilistico y aeronautico o para el sellado de juntas en la construccion de palas de rotores para aerogeneradores.The proposed device, as well as the combined nozzle preferably used with this device, can be used, for example, for sealing edges of door or window parts for applications in the automotive and aeronautical sector or for sealing joints in the construction of blades. of rotors for wind turbines.

Vi'as para realizar la invencionYou saw to make the invention
Un ejemplo de una boquilla combinada que se puede utilizar con el presente dispositivo esta representada en la figura 1 en diferentes vistas. La figura 1a muestra una vista isometrica de la boquilla combinada, en la que, en el lado de conexion, se reconocen la abertura del canal de boquilla -2- para la alimentacion del material viscoso y la abertura del canal de boquilla -4- para el abastecimiento de aire. La boquilla se estrecha hacia la punta de la boquilla, tal como se reconoce en la figura 1a.An example of a combined nozzle that can be used with the present device is shown in Figure 1 in different views. Figure 1a shows an isometric view of the combined nozzle, in which, on the connection side, the opening of the nozzle channel -2- for the feeding of the viscous material and the opening of the nozzle channel -4- are recognized for The air supply. The nozzle narrows toward the tip of the nozzle, as recognized in Figure 1a.
La figura 1b muestra una vista superior de esta boquilla desde el lado de conexion, en la que tambien se reconocen las aberturas posteriores hacia los canales de boquilla -2-, -4-. En este ejemplo, el diametro -D- de la boquilla en su punto mas ancho es de 18 mm, la longitud -L- de 25 mm.Figure 1b shows a top view of this nozzle from the connection side, in which the rear openings towards the nozzle channels -2-, -4- are also recognized. In this example, the diameter -D- of the nozzle at its widest point is 18 mm, the length -L- of 25 mm.
La figura 1 c muestra una vista de seccion a lo largo de la linea de corte -AA- de la figura 1 b. En esta vista de seccion se reconoce el recorrido de ambos canales de boquilla -2-, -4-, que terminan respectivamente en la abertura de boquilla -1- para el material viscoso y la abertura de boquilla -3- para la salida de aire. El canal de boquilla -4- para el flujo de aire esta inclinado en este ejemplo en un angulo de 4° respecto al canal de boquilla -2- para el material viscoso. Esta inclinacion es necesaria en este ejemplo para lograr que la abertura de boquilla -3- para la salida de aire se encuentre a una distancia reducida y optima por detras de la abertura de boquilla -1- para el material viscoso. En el presente ejemplo, esta distancia es de 4 mm (distancia central).Figure 1 c shows a sectional view along the cutting line -AA- of Figure 1 b. In this sectional view, the path of both nozzle channels -2-, -4-, respectively ending in the nozzle opening -1- for the viscous material and the nozzle opening -3- for the air outlet, is recognized . The nozzle channel -4- for the air flow is inclined in this example at an angle of 4 ° with respect to the nozzle channel -2- for the viscous material. This inclination is necessary in this example to ensure that the nozzle opening -3- for the air outlet is at a reduced and optimal distance behind the nozzle opening -1- for the viscous material. In the present example, this distance is 4 mm (center distance).
La figura 1d muestra una vista inferior de la boquilla, en la que se reconocen ambas aberturas de boquilla -1-, -3-, realizadas a modo de boquillas de ranura ancha. En este ejemplo, las aberturas de boquilla tienen respectivamente una anchura de 4 mm y una longitud de 1 mm, correspondiendo la direccion longitudinal a la direccion de separacion de ambas boquillas o a la direccion de avance -5- de la boquilla durante la aplicacion del material viscoso. La direccion de avance -5- esta indicada en las figuras 1c y 1d con una flecha.Figure 1d shows a bottom view of the nozzle, in which both nozzle openings -1-, -3-, made as wide slot nozzles are recognized. In this example, the nozzle openings respectively have a width of 4 mm and a length of 1 mm, the longitudinal direction corresponding to the direction of separation of both nozzles or to the direction of advance -5- of the nozzle during the application of the material viscous. The forward direction -5- is indicated in figures 1c and 1d with an arrow.
En la vista de seccion de la figura 1c tambien se reconoce el desnivel -d- entre la abertura de salida de aire -3- y la abertura de boquilla -1- para el material viscoso. En el presente ejemplo, este desnivel -d- es de 4 mm y es necesario para poder realizar un moldeado optimo del material viscoso aplicado a traves de la abertura de boquilla -1- sobre el canto de la pieza. Las dimensiones elegidas en este caso permiten aplicar un material muy viscoso, por ejemplo, un adhesivo epoxico con una viscosidad > 100 Pa-s, que tras la aplicacion es moldeado a traves de la abertura de boquilla de aire -3- a una forma con seccion plana practicamente de lente. Esta accion mejora considerablemente el recubrimiento del canto de la pieza durante la aplicacion del material viscoso. Debido a laIn the sectional view of figure 1c, the difference between the air outlet opening -3- and the nozzle opening -1- for the viscous material is also recognized. In the present example, this slope -d- is 4 mm and is necessary to be able to perform an optimal molding of the viscous material applied through the nozzle opening -1- on the edge of the piece. The dimensions chosen in this case allow to apply a very viscous material, for example, an epoxy adhesive with a viscosity> 100 Pa-s, which after application is molded through the air nozzle opening -3- to a shape with practically flat section of lens. This action considerably improves the coating of the edge of the piece during the application of the viscous material. Due to the

distancia reducida entre ambas aberturas de boquilla -1 -3-, la boquilla tambien puede utilizarse ventajosamente en huecos estrechos o en la zona de radios estrechos de la pieza.reduced distance between both nozzle openings -1 -3-, the nozzle can also be used advantageously in narrow gaps or in the narrow radius area of the part.
La figura 2 muestra un primer ejemplo de un dispositivo o un aplicador segun la presente invencion. El aplicador esta compuesto en este ejemplo por una palanca acodada -8-, cuya parte anterior constituye simultaneamente el soporte para la boquilla -10- y cuya parte posterior esta unida de forma fija a un robot a traves de una brida de robot -6- como elemento de conexion. La palanca acodada -8- permite un movimiento del brazo anterior con la boquilla -10- en direccion paralela a la normal a la superficie del canto de la pieza y presenta un muelle -7-, que presiona el soporte de boquilla o la boquilla con el rodillo guia -9- contra el canto de la pieza. La figura 2a muestra al respecto una vista isometrica de un aplicador de este tipo, en el que se reconocen la palanca acodada -8-, asi como la brida de robot -6-. A traves de un sensor laser -11-, cuyo rayo laser -12- esta representado de forma esquematica, se mide el movimiento de la palanca acodada -8-. Un movimiento de este tipo tiene lugar durante la aplicacion del material viscoso si el canto de la pieza presenta ciertas tolerancias y por tanto no se corresponde con la trayectoria programada. A traves de la medicion del movimiento de la palanca acodada se puede registrar la desviacion y corregir la trayectoria del robot de forma correspondiente.Figure 2 shows a first example of a device or an applicator according to the present invention. The applicator is composed in this example by a cranked lever -8-, whose front part simultaneously constitutes the support for the nozzle -10- and whose back part is fixedly attached to a robot through a robot flange -6- as connection element. The angled lever -8- allows a movement of the anterior arm with the nozzle -10- in a direction parallel to the normal to the surface of the edge of the piece and has a spring -7-, which presses the nozzle holder or the nozzle with the guide roller -9- against the edge of the piece. Figure 2a shows an isometric view of an applicator of this type, in which the angled lever -8-, as well as the robot flange -6- are recognized. Through a laser sensor -11-, whose laser beam -12- is schematically represented, the movement of the angled lever -8- is measured. Such a movement takes place during the application of the viscous material if the edge of the piece has certain tolerances and therefore does not correspond to the programmed trajectory. Through the measurement of the movement of the angled lever, the deviation can be recorded and the robot's trajectory corrected accordingly.
La figura 2b muestra una vista lateral de este aplicador, en la que se vuelven a reconocer la brida de robot -6-, la palanca acodada -8-, asi como el sensor laser -11-. En la parte anterior de la palanca acodada -8- esta representado en este ejemplo el rodillo guia -9-. En la figura tambien esta representada con una flecha la direccion de movimiento -13- de la palanca acodada -8-. La parte anterior de esta palanca acodada se reconoce aun mejor en la vista de detalle -B- de la figura 2e. El rodillo guia -9- presenta en este, asi como tambien en los otros ejemplos, un estrechamiento central con flancos crecientes en ambos lados, tal como se reconoce en la seccion de la figura 2e. De este modo se consigue un centrado de la boquilla -10-, dispuesta en direccion del avance detras del rodillo guia -9-, respecto al canto de la pieza. En la figura 2e solo se reconoce una pieza de alimentacion de la boquilla -10-, que termina en una zona posterior en un tubo flexible de material para la alimentacion del material viscoso.Figure 2b shows a side view of this applicator, in which the robot flange -6-, the bent lever -8-, as well as the laser sensor -11- are recognized again. The guide roller -9- is represented in this example on the front of the angled lever -8-. The direction of movement -13- of the angled lever -8- is also shown in the figure with an arrow. The front part of this bent lever is even better recognized in the detail view -B- of Figure 2e. The guide roller -9- presents in this, as well as in the other examples, a central narrowing with increasing flanks on both sides, as recognized in the section of Figure 2e. In this way a centering of the nozzle -10-, arranged in the direction of the advance behind the guide roller -9-, is achieved with respect to the part edge. In figure 2e only one feed piece of the nozzle -10- is recognized, which ends in a posterior area in a flexible tube of material for the feeding of the viscous material.
La figura 2c muestra una vista superior del aplicador, en la que, por un lado, se vuelve a reconocer la pieza de alimentacion de la boquilla y, por otro lado, tambien un muelle -7-, a traves del cual el rodillo guia -9- es presionado contra el canto de la pieza. La figura 2d vuelve a mostrar la parte anterior de la palanca acodada en detalle. Aqui se reconoce mas claramente la posicion de la boquilla -10- detras del rodillo guia -9-.Figure 2c shows a top view of the applicator, in which, on the one hand, the nozzle feed piece is recognized again and, on the other hand, also a spring -7-, through which the roller guides - 9- is pressed against the edge of the piece. Figure 2d shows again the front part of the lever angled in detail. Here the position of the nozzle -10- behind the guide roller -9- is more clearly recognized.
La figura 3 muestra otro ejemplo de una posible configuracion del aplicador propuesto. En este ejemplo, el aplicador permite un movimiento del soporte de boquilla o del cabezal de boquilla -15-, tanto en direccion paralela a la normal a la superficie del canto de la pieza, como tambien en direccion perpendicular a la direccion de avance y a la normal a la superficie. La figura 3a muestra una vista isometrica de este aplicador. El aplicador presenta un cabezal de boquilla -15- al que esta fijado el rodillo guia -9-. Este cabezal de boquilla tambien comprende la boquilla, que no se reconoce en esta vista. El cabezal de boquilla -15- esta unido a una placa de montaje -17-, que permite la fijacion del aplicador a un dispositivo de manipulacion, a traves de un muelle -18- y una guia ranurada -16-. En la vista lateral de la figura 3b se vuelven a reconocer la placa de montaje -17-, el muelle -18- y el cabezal de boquilla -15-. En esta vista tambien esta representado el tubo flexible de material -19-, a traves del cual se alimenta el material viscoso al cabezal de boquilla -15-.Figure 3 shows another example of a possible configuration of the proposed applicator. In this example, the applicator allows a movement of the nozzle holder or of the nozzle head -15-, both in a direction parallel to the normal surface of the piece, as well as in the direction perpendicular to the direction of advance and normal to the surface. Figure 3a shows an isometric view of this applicator. The applicator has a nozzle head -15- to which the guide roller -9- is fixed. This nozzle head also comprises the nozzle, which is not recognized in this view. The nozzle head -15- is attached to a mounting plate -17-, which allows the applicator to be fixed to a handling device, through a spring -18- and a grooved guide -16-. In the side view of figure 3b, the mounting plate -17-, the spring -18- and the nozzle head -15- are recognized again. In this view the flexible tube of material -19- is also represented, through which the viscous material is fed to the nozzle head -15-.
Finalmente, la figura 3c muestra una vista frontal de este aplicador, en la que tambien se reconocen ambas direcciones de movimiento del cabezal de boquilla -15- con el rodillo guia -9-, siendo la direccion de movimiento -13- una direccion paralela a la normal a la superficie del canto de la pieza, y la direccion de movimiento -14-, una direccion perpendicular a la direccion de avance y perpendicular a la normal a la superficie. La guia ranurada -16- hace posible la direccion de movimiento -14- perpendicular a la normal a la superficie. En la figura se reconocen los muelles -20-, a traves de los cuales el desplazamiento paralelo posible con la ranura retorna respectivamente a una posicion central. El muelle -18- sirve para presionar el rodillo guia -9- contra el canto de la pieza. La figura 3d muestra una vista inferior, en la que se reconoce la ubicacion de la boquilla -10- respecto al rodillo guia -9-.Finally, Figure 3c shows a front view of this applicator, in which both directions of movement of the nozzle head -15- are also recognized with the guide roller -9-, the direction of movement -13- being a direction parallel to the normal to the surface of the edge of the piece, and the direction of movement -14-, a direction perpendicular to the direction of advance and perpendicular to the normal to the surface. The grooved guide -16- makes the direction of movement -14- perpendicular to the normal to the surface possible. In the figure, the springs -20- are recognized, through which the possible parallel displacement with the groove returns respectively to a central position. The spring -18- serves to press the guide roller -9- against the edge of the piece. Figure 3d shows a bottom view, in which the location of the nozzle -10- with respect to the guide roller -9- is recognized.
Con un aplicador de este tipo se compensan las tolerancias de pieza en el canto de la pieza durante la aplicacion del material viscoso, tanto en direccion paralela a la normal a la superficie, como tambien en direccion perpendicular a esta, gracias a la correspondiente posibilidad de movimiento del propio aplicador, de forma que no es necesario utilizar un costoso sistema de sensores para una correccion de la trayectoria del dispositivo de manipulacion.With an applicator of this type, the work tolerances in the workpiece edge are compensated during the application of the viscous material, both in a direction parallel to the normal to the surface, and also in the direction perpendicular to it, thanks to the corresponding possibility of movement of the applicator itself, so that it is not necessary to use an expensive sensor system for a correction of the handling device path.
Otra posibilidad de configuracion del aplicador propuesto esta representada en la figura 4 en diferentes vistas. Esta configuracion representa un aplicador manual para el sellado de cantos en radios estrechos y huecos de piezas. El aplicador esta conectado directamente a una pistola de cartuchos neumatica -21-, tal como se reconoce en la vista isometrica de la figura 4a. El propio aplicador presenta un correspondiente elemento de conexion -22-, que esta unido al soporte de boquilla -24-, en el presente ejemplo tambien denominado “cabezal del aplicador”, a traves de una guia en paralelogramo -23-. La figura 4b muestra al respecto otra vista lateral y la figura 4c, una vista superior del aplicador conectado a la pistola de cartuchos -21 -. En la figura 4d se reconoce la vista parcial -A- de la figura 4b. Esta figura muestra la guia en paralelogramo -23-, el soporte de boquilla -24-, asi como una parte de la boquilla -10- del aplicador. A la parte anterior esta fijado un rodillo guia -9- para guiar la boquilla a lo largo del canto de la pieza. La guia en paralelogramo permite a su vez un movimiento de la boquilla en la direccion de movimiento -13- indicadaAnother possibility of configuring the proposed applicator is represented in Figure 4 in different views. This configuration represents a manual applicator for sealing edges in narrow and hollow radii of parts. The applicator is directly connected to a pneumatic cartridge gun -21-, as recognized in the isometric view of Figure 4a. The applicator itself has a corresponding connection element -22-, which is attached to the nozzle holder -24-, in the present example also called the "applicator head", through a parallelogram guide -23-. Figure 4b shows in this regard another side view and Figure 4c, a top view of the applicator connected to the cartridge gun -21 -. Figure 4d shows the partial view -A- of Figure 4b. This figure shows the parallelogram guide -23-, the nozzle holder -24-, as well as a part of the nozzle -10- of the applicator. A guide roller 9 is attached to the front part to guide the nozzle along the edge of the piece. The parallelogram guide in turn allows a movement of the nozzle in the direction of movement -13- indicated

con la flecha, paralela a la normal a la superficie del canto de la pieza. El rodillo guia -9- se consigue a traves del efecto muelle de un muelle montado en la guia en paralelogramo -23-. La boquilla -10- esta unida con la pistola de cartuchos -21 - a traves de un tubo flexible de material -19-.with the arrow, parallel to the normal surface of the piece. The guide roller -9- is achieved through the spring effect of a spring mounted on the guide in parallelogram -23-. The nozzle -10- is connected with the cartridge gun -21 - through a flexible tube of material -19-.
Para la aplicacion de un material viscoso, el aplicador es colocado con el rodillo guia -9- sobre el canto de la pieza y se presiona el boton de arranque -25- de la pistola de cartuchos -21-. A continuacion, el material viscoso sale de la boquilla mientras el operador desplaza simultaneamente el aplicador con el rodillo guia a lo largo del canto de la pieza. Debido al gran rango de ajuste posible en direccion paralela a la normal a la superficie del canto de la pieza gracias a la guia en paralelogramo, el aplicador, gracias al efecto muelle, compensa perfectamente las inexactitudes de movimiento del operador, de forma que en todo momento se garantiza una separacion constante entre la boquilla y el canto de la pieza. Finalmente, la figura 4e muestra el detalle -B- de la figura 4c, en el que se reconoce la disposicion de la boquilla -10- inmediatamente detras del rodillo guia -9-.For the application of a viscous material, the applicator is placed with the guide roller -9- on the edge of the piece and the starter button -25- of the cartridge gun -21- is pressed. Next, the viscous material leaves the nozzle while the operator simultaneously moves the applicator with the guide roller along the edge of the part. Due to the wide range of adjustment possible in a direction parallel to the normal surface of the part of the piece thanks to the guide in parallelogram, the applicator, thanks to the spring effect, perfectly compensates the inaccuracies of the operator's movement, so that in all moment a constant separation between the nozzle and the edge of the piece is guaranteed. Finally, Figure 4e shows the detail -B- of Figure 4c, in which the arrangement of the nozzle -10- immediately behind the guide roller -9- is recognized.
En el aplicador propuesto, la forma de la seccion del rodillo guia puede presentar diferentes geometrias. Especialmente si el rodillo guia se dispone en direccion de avance detras de la boquilla, la eleccion adecuada de la geometria o la forma del rodillo, en combinacion con la velocidad de avance a lo largo de la pieza y el caudal volumetrico del material viscoso, permite adaptar la geometria del cordon de forma precisa a las especificaciones mediante el rodillo guia. La figura 5 muestra al respecto, y solo a modo de ejemplo, algunas formas posibles del rodillo. Las relaciones de anchura y diametro de los segmentos individuales del rodillo guia -9-, que se reconocen en la figura y pueden presentar, por ejemplo, una anchura de 8 mm y a ambos lados un diametro de 6 mm, naturalmente pueden variar en funcion de la aplicacion.In the proposed applicator, the shape of the guide roller section may have different geometries. Especially if the guide roller is arranged in the direction of advance behind the nozzle, the appropriate choice of the geometry or the shape of the roller, in combination with the speed of advance along the part and the volumetric flow of the viscous material, allows adapt the geometry of the cord precisely to the specifications using the guide roller. Figure 5 shows in this regard, and only by way of example, some possible forms of the roller. The width and diameter ratios of the individual segments of the guide roller -9-, which are recognized in the figure and can, for example, have a width of 8 mm and on both sides a diameter of 6 mm, can naturally vary depending on the application.
